Antipredator behavior can depend on the internal state of an individual prey. Long-term chronic stress due to natural or human-induced environmental alterations can cause detrimental effects in animals, which may increase vulnerability to predators. Consequently, prey should modify their risk assessment and responses to predators. Here, we examined experimentally whether, and to what extent, the internal state of an animal aff...

The efficacy of sexual signals in communication is often maximized under specific environmental conditions. Anthropic alterations of these conditions might, thus, negatively affect communication during reproductive behavior. In fossorial animals, inhabiting visually restricted environments, chemical senses are very important. We examined whether climatic episodes of heat-waves with unusual high temperatures may affect the info...
